SPECIFICATION forming part of Letters Patent N o. 729,477, dated May 26,1903. Application'led October 24, 1902l Serial N9. 128,573. (No model.)

T0 @ZZ 'Lu/1,0m it may concern/f 1 Be it known that I, RUDOLPHG.W1RTALLA, a citizen of the UnitedStates, and a resident of the city ofNew York, (Long Island City,

borough of Queens,) in the county ofv Queens and State of New York, haveinvented a new and Improved Loom Heddle-Frame, of which the following isa full, clear, and exact description.

My invention relates to improvements in loom heddle-frames of thatclasswherein a series of heddles are strung on heddle-bars, the latter beingstayed in'placeby hooks attached to the end portions of the frame.Heretofore considerable difficulty has been experienced by operators inadjusting the heddles Within the frame and in applying or removing theheddles. This is due, primarily, to the attachment of the stay-hooks t0the frame in a substantially permanent way, and this makes it necessaryfor the operator to forcibly lift the heddle-bars over the hooks, whichpractice is objectionable 'for two reasons: First, the heddles arestrained or stretched lengthwise to such an extent that they arefrequently broken or made useless, and, secondly, the application offorce by the hands hurts them to such an extent that operators object tochanging the heddles. j

The object that I have in View is to provide means by which theadjustment, removal, and insertion of .the heddles can be easily,quickly, and readily performed without hurting the hands of theoperator, because it is not necessary tojforci bly lift the heddle-barsand strain the heddles strung thereon. I attain these objects by theemployment of a stay-hook which is removably attached to theheddle-frame and is easily slipped from engagement with the heddlebars.

Further objects and advantages of the iii- Vention will appear in thecourse of the subjoined description, and the novelty will be fragmentaryview-in elevation illustrating another embodiment of the invention.

5 designates an ordinary loom heddle-frame provided with detachableheddle-bars 6, the latter spanning the frame near the end portionsthereof and secured removably to the side rails of the frame by anysuitable means known to the art. On'the supporting-bars 6 are threadedany desired number of heddles 7, each having an eye 8, said heddlesbeing of any suitable construction and fitted loosely on the bars 6.

In this art it is customary to employ means which serve to brace or staythe heddle-supporting bars 6. 'The stay means are usually in the form ofhooks, which engage with the bars 6 and are fastened to the frame; butordinarily the stay hooks are fastened to the frame in s uch a way thatthey cannot be easily detached when it is desired to adjust or inter-.11, and through the eyes of the series of hooks 9 is 'passed a rod 12,the latter being fastened removably to the frame 5. This rod is bracedby the employment of eyes on the frame,one of said eyes being indicatedat 13 in Fig. 1, although it will be understood that a series of theeyes is attached to each end bar of theV frame in a position for the rod12 to pass therethrough. The rod may be fastened removably to the sidebars of the frame in any suitable way; but, as shown by Fig. 1, the endportions of this rod are provided with nuts 14, which are screwed onsaid rod and bind against the outer edges of the frame.

The series of stay-hooks are fitted loosely on the rod 12 in a way Vtohave a slidable movement thereon, and the entire series of these .hooksmay be disconnected simply by remov- ICO permitting either bar to beremoved from the heddle-frame easily and quickly in order to interchangethe heddles or increase or decrease the number thereof, as may bedesred.

The employment of a single rod in connection with a series of stay-hooksserves to attach the series detachably to the frame; but my invention isnot restricted to this attachment of the stay-hooks in series, because Iam aware that the stay-hooks may be connected individually to the framein a Way to facilitate the removal thereof. One embodiment of meansforindividually fasteningr the stay-hooks to the frame is represented byFig. 3, wherein each stay-hook 9 is loosely and slidably fitted on ahorizontal bolt 15, supported in a pair of eyes 16, that are fastened tothe end rail of the frame. One end of the rod or bolt 15 is providedwith a head 17, while its other end receives a nut 18. In thisconstruction the stay-hook 9 is free to slide on the rod or bolt 15between the pair of eyes 16, and said rod or bolt 15 can easily bedetached from the eyes by removing the nut 18 and withdrawing the rod orbolt endwise, thus disconnecting the stay-hook 9 from the end bar of theframe and permitting the hook to be readily slipped away from theheddle-supporting bar 6.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. Aloomheddle-framehavingheddle-supporting bars, arod or bolt fastened removably to said frame, and a stay-hook fitted tosaid rod or bolt and the heddle-supporting bar, whereby the rod or boltmay be withdrawn from the frame and the hook may be slippedv fromengagement with the heddlesupporting bar.

2. Aloom heddle-framehavingheddle-supporting bars, a series ofstay-hooks engaging with said bars, and a rod or bolt secured removablyto the frame, said stay-hooks being threaded on the rod or bolt andadapted on the Withdrawal of said rod to be easily disengaged from theheddle-supporting bar.

3. Aloom heddle-framehavingheddle-supporting bars, a removable rod orbolt attached to said frame, and a stay-hook loosely and slidably fittedon said rod or bolt and engaging removably with the heddle-supportingbar.

4. A looln heddle-frame having a heddlesnpporting bar, a rod or boltsecured removably to the frame, an eye fastened to the frame andengaging said rod or bolt, and stay-hooks threaded on the rod or boltand engaging the lleddle-supporting bar.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
